The compat4x installs the libraries in /usr/lib/compat.
kargl[202] ldd /usr/local/lib/NAGWare/f95
/usr/local/lib/NAGWare/f95:
libm.so.2 => /usr/lib/libm.so.2 (0x28075000)
libc.so.4 => /usr/lib/compat/libc.so.4 (0x28092000)
What does ldd report for the binaries that die?

No. The reason for the version number bump from 4 to 5 is
an ABI/API has changed. In this case, _stdinp, _stdoutp,
and _stderrp have changed.

5.0 isn't recommended for production servers.
